BO4 needs to make a good comeback. BO1 was such a big hit, and its success was the biggest reason we are on number 4. BO2 was a decent game, not as loved as BO1, but still one of my top favorites. BO3 was a major letdown. I'm excited to see how BO4 plays out. The gameplay video released some interesting things that are coming back, new to the game, and I'm excited to see how it plays out.
